What makes ultra-high performance concrete (uhpc) a special material?

Gheorghe-Alexandru Bărbos

Rezumat/Abstract. Ultra - High Performance Concrete (UHPC) is a special material with compressive strength higher than 150 MPa and an increased durability, which is reflected in its name. Besides its high - strength it has an enhanced ductility, due to the presence of steel fibers in the concrete matrix. It can be used as structural material for buildings located in areas with high seismic risk and also in marine or industrial (where chemical attack is possible) environments. This type of concrete is still in the research-development stage, no design standard being available.
